Electronics S1W8: Series-Parallel Resistor Combinations

How to use Ohm's Law, Kirchhoff's Voltage and Current Laws, to solve series-parallel resistor circuit problems.

What you'll learn

Determine which electronics principle of Ohm's Law, Kirchhoff's Voltage Law and Kirchhoff's Current Law apply to a given resistive circuit problem.

Solve circuit problems using the voltage divider formula and the current divider formula.

Correctly solve for all of the characteristics (voltage, current and resistance) in a series-parrallel resistor circuit.

Requirements

To do well you need to successfully one of the two following prerequisites: 1) A solid foundation of Ohm's Law, Kirchhoff's Voltage and Current Laws, the Voltage Divider and Current Divider Formulas, and the ability to solve simple series and parallel resistive circuits, or 2) Complete the previous weeks of training connected to this course. (They all start with "Electronics SxWy" where "x" is the Semester number, [1 for the previous 7 weeks and this week] and "y" is the Week Number.)

Description

This course is Week 8 of an 8 week series that teaches electronics to professionals, students and hobbyists desiring to know how electronic circuits work. This first 8 weeks has the name "DC Electronics" in most college electronics degree programs because it teaches the following concepts about electronics:- The atomic structure of conductors, insulators and semiconductors- The definition of the major characteristics of electronics: Resistance, Current, Voltage and Power- The use of Ohm's Law, Kirchhoff's Voltage and Current Laws, the Voltage Divider and Current Divider Formulas and how to apply them to basic resistive circuits.- Practice solving series resistive circuits, parallel resistive circuits, and the topic for this week's class: solving series-parallel resistive circuits.The class is presented primarily as a PowerPoint presentation with instruction by your teacher.Quizzes are presented at the end of each section of the course to test your knowledge and comprehension of the material presented in that section.
